Minimally Invasive Hysterectomy Rates in Québec: Trends Over the Last Decade and Predictors of Technicity

To assess trends and predictors of a high technicity index for hysterectomies performed in the province of Québec.We conducted a retrospective study using the ADAM database to determine the annual number hysterectomies performed for a suspected benign condition and the surgical approach used across 81 hospitals in the province of Québec from 2007 to 2017. We calculated the technicity index for each hospital and analyzed trends in surgical approach using the Cochran-Armitage test. We used logistic regression to assess potential predictors of a high technicity index (70%), including academic centre, urban area, high volume of hysterectomies performed, and greater number of gynaecologists per hospital.Fifty-nine hospitals were eligible for inclusion, representing 96 431 hysterectomies during the study period. Over the decade, the technicity index increased from 43% to 66% (P 0.001, with a 198% increase in laparoscopic hysterectomies (from 685 to 2039 per year; P 0.001), a 50% decrease in abdominal hysterectomies (from 5528 to 2790 per year; P 0.001), and a 8% decrease in vaginal hysterectomies (form 3551 to 3257 per year; P 0.001). Meanwhile, the total number of hysterectomies per year declined by 17% (P 0.001). Being an academic centre was the only significant predictor of a high technicity index70% (68% vs. 38%; OR 7.5; P = 0.047).Technicity is increasing in the province of Québec and the majority of hysterectomies are now performed using a minimally invasive approach. This shift has mainly occurred through an increase in the laparoscopic approach and a decrease in the abdominal approach. Academic centres are more likely to have high technicity indexes.
